Abstract (en)
[origin: EP3339922A1] The present invention provides an optical chip 100 and a method 600 for coupling light. The optical chip 100 comprises an input edge coupler 101 having at least one input waveguide 102, and configured to receive light on two orthogonal modes of same polarization. It further comprises a demultiplexer 103 configured to divide the two orthogonal modes into a mode carried on a first intermediate waveguide 104 and a mode carried on a second intermediate waveguide 105 independent from the first intermediate waveguide 104. The optical chip 100 also comprises a polarization multiplexer 103 configured to recombine the modes carried on the intermediate waveguides 104, 105 into two polarization-orthogonal modes carried on one output waveguide 107.
